UNITED STATES PATENT Erica CHARLES SOHREBLER, OF METHUEN, MASSACHUSETTS,ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE OWVASCO COMPANY, OF PORTLAND,MAINE.

APPARATUS FOR CARBONIZING THE VEGETABLE MATTER IN WOOL.

SPECIFICATION forming part of Letters Patent No. 380,598, dated April 3,1888.

(No model.)

To all 2072 0122 it may concern:

Be it known that I, CHARLES SCHREBLER, of Methuen, in the county ofEssex and State of Massachusetts, have invented certain new and usefulImprovements in Apparatus for Drying and Garbonizing Wool, of which thefollowing is a specification.

My invention relates to those modes or processes of and means fortreating wool for the removal of burrs and other vegetable substances,involving the use of chemicals, and in which the foreign vegetablematter is carbonized and subsequently granulated or pulverized and blownout of the wool.

It is the general purpose of my invention to provide improved meanswhereby the art of carbonizing vegetable matter in wool may bepracticed, and particularly to provide means whereby the mode ofprocedure set forth in an application filed by me October 31, 1887, maybe carried out.

My present invention comprises a machine adapted to effect first thethorough drying of the wool and subsequently the carbonization of thevegetable matter in the wool without disturbing the latter after it isplaced in the machine, the two acts being successivelypracticed underdifferent degrees of temperature.

I will first describe myimprovements in connection with the drawings andthe letters of reference marked thereon, forming a part of thisspecification, particularly pointing out the invention in the claimshereto appended.

Of the drawings, Figure 1 represents a front elevation of my improveddrying and carbonizing machine. Fig. 2 representsa longitudinalsectional view thereof. Fig. 3 represents a horizontal section on theline y y of Fig. 1. Fig. 4 represents a vertical section on the line a;:c of Fig. 1.

Similar letters of reference designate similar parts wherever theyoccur.

In carrying out my invention I construct a closed casing, a, forming atone end thereof a chamber, Z), extending from the top to the bottom. Inthe main chamber 0, near the top thereof, I arrange a series or bed ofpipes, d, adapted to have steam or hot air passed therethrough orcirculated therein, which pipes are placed quite closely together,though not so that air may not pass between any two of them.

6 6 indicate drawers provided with foraminous bottomsf, which drawersare arranged below the pipes d, and are adapted to be drawn out in frontof the casing to receive the wool 5 to be treated and then slid intoplace in the machine.

9 indicates a suction-fan supported on a rotary shaft, h, provided withsuitable bearings,

i, said fan being arranged in an aperture, j, made in the partition 7c,separating chamber 1) from main chamber a at a point below the drawers6.

Zindicates a port oraperture made in the casing a, above pipes d, andadapted to be closed or opened by a slide or valve, m.

n is a slide or valve in chamber b, above fan 9, adapted to be closed tocut off circulation of air in said chamber between the upper and lowerportions thereof, or to be closed, and so 7:) permit free circulation ofair therein.

0 indicates a slide or valve in chamber b, preferably on the samehorizontal plane as fan 9 and below slide m, permitting the air in saidchamber to be forced out therefrom, or by the 5 closing of the slide toprevent such operation.

19 represents a port or aperture in partition k, above pipes d andopposite port or aperture Z, for a purpose to be presently explained.

Shaft hand its attached fan 9 may be ro- 8o fated by any suitable means,a pulley, q, being in the present instance shown as employed for thatpurpose.

The wool to be treated, after being subjected to a chemical solution forthe purpose of as- 85 sisting to destroy the vegetable matter therein,is placed evenly in the withdrawn drawers 6, which drawers are afterwardslid into place in the machine. Steam or hot air being now admitted topipes d, I close slide-valve a, open 0 slide-valves m and 0, and rotatesuction-fan g, with the result of drawing the fresh cool air into themachine through port or aperture Z and through the bed of heated pipesd, by which the air is heated to a temperature of, say, from 9 5 toFahrenheit, whence it is sucked or drawn through the wool by fan g anddischarged through the port or aperture made by the raising ofslide-valve 0. This operation is kept up for, say, one hour and a half,to effect I00 a thorough drying of the wool, and to avoid thepossibility of the sweating or yellowing of the material being'treated.After the Wool has been completely dried, as aforesaid, I closeslide-valve 0, open slide-valve n, and close valve m about threequartersof the way, when suction-fan g is rotated with the effect of drawing theair in chamber 0 down through the bed of heated pipes d and through thewool and sending it up through chamber 12 and out and through port oraperture 19 into chamber 0, to be again reheated on its passage throughthe bed of pipes d. In this way I can quickly run the air thus revolvedin the machine up to a temperature of, say, from 175 to 180 Fahrenheit,which is sufficient to effect a thorough and complete carbonization ofall vegetable matter in the wool, after it has been preliminarilytreated, as aforesaid, in about one-half hour. It will be understoodthat this operation of revolving or circulating the heated air in themachine is kept up until the wool is discharged from the drawers 6.

r indicates a thermometer placed within the casing behind a glass, toenable me to watch the temperature to which the air in the machine isheated in the carbonizing process, the

degree of such heating being regulated by the position of slide-valve min aperture Z, whichgoverns the amount of cool air let into the chamber0.

The wire-gauze or foraminous bottoms in drawers 6 and the uniform amountof material placed in the drawers, together with the fact that air isdrawn through the entire body of wool, insures a uniform treatment ofthe mass and renders it unnecessary to stir or otherwise disturb thewool from the time it is placed in the machine until the vegetablematter therein is completely carbonized and it is ready to be removedand subjected to any process for crushing the burrs, &c., and blowing orotherwise dusting them out of the mass.

3 represents a door-by which accessmay be gained to the chamber a, and ta door for a like purpose in chamber 1).

Although I have been particular to describe I the form and arrangementof the several parts i or elements of the invention as here shown, it isobvious that these may be varied without departing from the nature orspirit of the invention, and that some of the parts may be used withoutthe presence of others.

Having thus described my invention, what I claim as new is- 1. In a wooldrying and carbonizing machine, the combination,with theinclosing-casing and a support or supports for the wool, of a fan forcreating a circulation of air in the casing, having its inlet andexhaust on different sides of the wool, a heater located on the sidefrom which the air passes through the wool, an air-port and a valve forclosing it between the fan and heater opposite the wool, an air-port anda valve for closing it on the side of the wool 'opposite the heater, anda valve for cutting off communication between the fan and heater,substantially as described. 7

2. A wool drying and carbonizing'machine having air inlet and outletports, slides for opening and closing said ports, chambers b c, thepartition between said chambers, port 1;, fan 9, valve 12, in chamber1), a bed of pipes, d, and a series of-drawers, 6, having foraminousbottoms, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 14th day of July, A. D. V1887.

CHARLES SCHREBLER.
